Hi,
Thank you for posting your query.
It is unfortunate that you have developed multiple medical problems, and on are multiple medications.
However, I appreciate your ability to cope with them and lead a good life.
Cognitive dysfunction, in your case, is related to the
brain tumor and effects of
radiation on the brain.
You would benefit from
psychotherapy, cognitive training, and regular exercises.
I hope my answer helps. Please get back if you have any follow up queries or if you require any additional information.
Wishing you good health,
Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology)
